Champion jockey Damien Oliver will remain in Australia for now after his contract to ride in Mauritius fell through.

Oliver, who took his Group One tally to 110 when he won the All Aged Stakes on Tivaci at Randwick yesterday, was due to depart this week to take up a contract on the island nation.

"I've actually just got some bad news.....it's fallen through," Oliver said. "The stable I was going to ride for were unable to have a stable jockey."

Oliver said he was unlikely to return to Sydney next week to ride in the rescheduled Sydney Cup.

He was one of six jockeys unaware last week's race had been called off midway through when riding the Lloyd Williams-owned Assign.
